==Introduction==

It is very important to regulate the bodies sodium level.  If it falls too low then water and ECF volumes also fall and sodium dependant transporters are also disturbed.  If it rises too far the transport systems are still disturbed but body water and ECF volume increases.  Sodium is therefore maintained within near constant parameters.  With the amount being excreted/lost corresponding to that ingested. Salt intake is not really regulated and thus it falls to the kidneys to maintain salt levels via excretion.
